This is a different case. The original report used qemu-img create in
step 2, which results in a sparse image that refers to the backing file
for all data. Your sequence has qemu-img convert instead, which fully
populates disk.qcow. Therefore, in step 3, qemu-img convert leaves the
full allocation
My mistake. It's different case than mine. Above sequence (original
report) works fine.
But I do not really understand why the same is not achieved in my case.
I use the convert instead of the create to get a full image in qcow
format. From that point, the desired behaviour is to create a qcow
Is this reintroduced? I am on version 2.3.0
$ dd if=/dev/urandom of=disk bs=1M count=1024
$ qemu-img convert -f raw -O qcow2 disk disk.qcow
$ qemu-img convert -f raw -O qcow2 -o backing_file=disk.qcow disk
disk1.qcow
$ ls -l
total 3146388

Status in
It is possible to chain backing files. As a workaround you could do the
following:
$ qemu-img create -f qcow2 -b 2.img 4.img # from now on don't modify 2.img,
instead use 4.img
$ qemu-img create -f qcow2 -b 2.img 3.img # here is the 3.img you tried to
create with qemu-convert
Images 1.img and
Do you confirm this as a bug?
